Urinary undiversion for pelvic actinomycosis: A long-term follow up

Background: A 43-year-old woman who had been using intrauterine contraceptive devices for the past 10 years underwent an emergency operation for bowel and urinary obstruction. Methods/Results: Frozen section analysis showed undifferentiated adenocarcinoma. Incomplete tumorectomy, ileal resection, partial cystectomy, colostomy and bilateral ureterocutaneostomy were palliatively performed. Postoperatively, periodic acid-Schiff and Grocott-Gomori methenamine tests revealed Actinomyces and the final diagnosis was pelvic actinomycosis. Treatment with penicillin G administered intravenously relieved her symptoms and the lesion was dramatically improved. The patient underwent colostomy closure and urinary undiversion. Conclusions: Five years after urinary undiversion, the patient's renal function has been maintained and she can void without incontinence and dysuria.
